Fire Alarm System Limitations

While a fire alarm system may lower insurance rates, it is not a substitute for fire insurance!

An automatic fire alarm system—typically made up of

smoke detectors, heat detectors, manual pull stations, audible

warning devices, and a fire alarm control panel with remote

notification capability—can provide early warning of a develop-

ing fire. Such a system, however, does not assure protection

against property damage or loss of life resulting from a fire.

The Manufacturer recommends that smoke and/or heat detec-

tors be located throughout a protected premise following the

recommendations of the National Fire Protection Association

Standard 72 (NFPA 72), manufacturer's recommendations,

State and local codes, and the recommendations contained in

the Guides for Proper Use of System Smoke Detectors, which

are made available at no charge to all installing dealers.

These documents can be found at http://www.systemsen-

sor.com/html/applicat.html. A study by the Federal Emer-

gency Management Agency (an agency of the United States

government) indicated that smoke detectors may not go off in

as many as 35% of all fires. While fire alarm systems are

designed to provide early warning against fire, they do not

guarantee warning or protection against fire. A fire alarm sys-

tem may not provide timely or adequate warning, or simply

may not function, for a variety of reasons:

Smoke detectors may not sense fire where smoke cannot

reach the detectors such as in chimneys, in or behind walls, on

roofs, or on the other side of closed doors. Smoke detectors

also may not sense a fire on another level or floor of a building.

A second-floor detector, for example, may not sense a first-

floor or basement fire.

Particles of combustion or “smoke” from a developing fire

may not reach the sensing chambers of smoke detectors

because:

• Barriers such as closed or partially closed doors, walls, or

chimneys may inhibit particle or smoke flow.

• Smoke particles may become “cold,” stratify, and not reach

the ceiling or upper walls where detectors are located.

• Smoke particles may be blown away from detectors by air

outlets.

• Smoke particles may be drawn into air returns before

reaching the detector.

The amount of “smoke” present may be insufficient to alarm

smoke detectors. Smoke detectors are designed to alarm at

various levels of smoke density. If such density levels are not

created by a developing fire at the location of detectors, the

detectors will not go into alarm.

Smoke detectors, even when working properly, have sensing

limitations. Detectors that have photoelectronic sensing

chambers tend to detect smoldering fires better than flaming

fires, which have little visible smoke. Detectors that have ion-

izing-type sensing chambers tend to detect fast-flaming fires

better than smoldering fires. Because fires develop in different

ways and are often unpredictable in their growth, neither type

of detector is necessarily best and a given type of detector

may not provide adequate warning of a fire.

Smoke detectors cannot be expected to provide adequate

warning of fires caused by arson, children playing with

matches (especially in bedrooms), smoking in bed, and violent

explosions (caused by escaping gas, improper storage of

flammable materials, etc.).

Heat detectors do not sense particles of combustion and

alarm only when heat on their sensors increases at a predeter-

mined rate or reaches a predetermined level. Rate-of-rise

heat detectors may be subject to reduced sensitivity over time.

For this reason, the rate-of-rise feature of each detector

should be tested at least once per year by a qualified fire pro-

tection specialist. Heat detectors are designed to protect

property, not life.

IMPORTANT! Smoke detectors must be installed in the

same room as the control panel and in rooms used by the sys-

tem for the connection of alarm transmission wiring, communi-

cations, signaling, and/or power. If detectors are not so

located, a developing fire may damage the alarm system, crip-

pling its ability to report a fire.

Audible warning devices such as bells may not alert people

if these devices are located on the other side of closed or

partly open doors or are located on another floor of a building.

Any warning device may fail to alert people with a disability or

those who have recently consumed drugs, alcohol or medica-

tion. Please note that:

• Strobes can, under certain circumstances, cause seizures

in people with conditions such as epilepsy.

• Studies have shown that certain people, even when they

hear a fire alarm signal, do not respond or comprehend the

meaning of the signal. It is the property owner's responsi-

bility to conduct fire drills and other training exercise to

make people aware of fire alarm signals and instruct them

on the proper reaction to alarm signals.

• In rare instances, the sounding of a warning device can

cause temporary or permanent hearing loss.

A fire alarm system will not operate without any electrical

power. If AC power fails, the system will operate from standby

batteries only for a specified time and only if the batteries have

been properly maintained and replaced regularly.

Equipment used in the system may not be technically com-

patible with the control panel. It is essential to use only equip-

ment listed for service with your control panel.

Telephone lines needed to transmit alarm signals from a

premise to a central monitoring station may be out of service

or temporarily disabled. For added protection against tele-

phone line failure, backup radio transmission systems are rec-

ommended.

The most common cause of fire alarm malfunction is inade-

quate maintenance. To keep the entire fire alarm system in

excellent working order, ongoing maintenance is required per

the manufacturer's recommendations, and UL and NFPA stan-

dards. At a minimum, the requirements of NFPA 72 shall be

followed. Environments with large amounts of dust, dirt or

high air velocity require more frequent maintenance. A main-

tenance agreement should be arranged through the local man-

ufacturer's representative. Maintenance should be scheduled

monthly or as required by National and/or local fire codes and

should be performed by authorized professional fire alarm

installers only. Adequate written records of all inspections

should be kept.

Installation Precautions

Adherence to the following will aid in problem-free installation with long-term reliability:

WARNING - Several different sources of power can be

connected to the fire alarm control panel. Disconnect all

sources of power before servicing. Control unit and associ-

ated equipment may be damaged by removing and/or insert-

ing cards, modules, or interconnecting cables while the unit is

energized. Do not attempt to install, service, or operate this

unit until manuals are read and understood.

CAUTION - System Re-acceptance Test after Software

Changes: To ensure proper system operation, this product

must be tested in accordance with NFPA 72 after any pro-

gramming operation or change in site-specific software. Re-

acceptance testing is required after any change, addition or

deletion of system components, or after any modification,

repair or adjustment to system hardware or wiring. All compo-

nents, circuits, system operations, or software functions known

to be affected by a change must be 100% tested. In addition,

to ensure that other operations are not inadvertently affected,

at least 10% of initiating devices that are not directly affected

by the change, up to a maximum of 50 devices, must also be

tested and proper system operation verified.

This system meets NFPA requirements for operation at 0-49º

C/32-120º F and at a relative humidity 93% ± 2% RH (non-

condensing) at 32°C ± 2°C (90°F ± 3°F). However, the useful

life of the system's standby batteries and the electronic com-

ponents may be adversely affected by extreme temperature

ranges and humidity. Therefore, it is recommended that this

system and its peripherals be installed in an environment with

a normal room temperature of 15-27º C/60-80º F.

Verify that wire sizes are adequate for all initiating and indi-

cating device loops. Most devices cannot tolerate more than a

10% I.R. drop from the specified device voltage.

Like all solid state electronic devices, this system may

operate erratically or can be damaged when subjected to light-

ning induced transients. Although no system is completely

immune from lightning transients and interference, proper

grounding will reduce susceptibility. Overhead or outside aerial

wiring is not recommended, due to an increased susceptibility

to nearby lightning strikes. Consult with the Technical Ser-

vices Department if any problems are anticipated or encoun-

tered.

Disconnect AC power and batteries prior to removing or

inserting circuit boards. Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filing,

reaming, or punching of the enclosure. When possible, make

all cable entries from the sides or rear. Before making modifi-

cations, verify that they will not interfere with battery, trans-

former, or printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs. Over-

tightening may damage threads, resulting in reduced terminal

contact pressure and difficulty with screw terminal removal.

This system contains static-sensitive components.

Always ground yourself with a proper wrist strap before han-

dling any circuits so that static charges are removed from the

body. Use static suppressive packaging to protect electronic

assemblies removed from the unit.

Follow the instructions in the installation, operating, and pro-

gramming manuals. These instructions must be followed to

avoid damage to the control panel and associated equipment.

FACP operation and reliability depend upon proper installation.

Audio Command Center Series Manual — P/N 51889:E1 6/8/2010 13

Section 1: Product Description

The ACC-25/50 Series consists of the AUDIO•COMMAND•CENTER•25/50 (ACC-25/50), the

AUDIO•COMMAND•CENTER•25/50 Zone System (ACC-25/50ZS), and the AUDIO•COM-

MAND•CENTER•25/50 Zone System with Telephone (ACC-25/50ZST) which are single channel,

25 watt, 25 VRMS, emergency voice evacuation panels. The ACC-25/50 provides up to two

speaker circuits while the ACC-25/50ZS and ACC-25/50ZST support up to eight speaker circuits.

Each panel provides the ability to record five field programmable messages (up to 60 seconds total

message duration) with an integral microphone or from an external audio source. An integral

power supply with battery charger supplies operational power. An ACC-AAM25 audio amplifier is

provided standard with each base unit. An optional second ACC-AAM25 amplifier is also avail-

able for backup purposes or to provide an additional channel of 25 watts. Optional 70 VRMS con-

version modules are also available for installations where 70 VRMS speakers are to be installed or

already exist. An optional External Page Module (ACC-EPM) is available for interfacing to nonfire

paging systems. The modular design allows for ease-of-serviceability.

Automatic activation of the ACC-25/50 by an FACP is possible via the five Command Input Cir-

cuits (CMD). The ACC-25/50ZS and ACC-25/50ZST can be automatically activated by the CMD

inputs or via the ACS serial communications link from the MS-9600, MS-9200UDLS, MS-

9200UD, MS-9200(E) and MS-5210UD FACPs.

Two Command Input Circuits can be independently field programmed for activation by an FACP

Notification Appliance Circuit reverse polarity or by closure of a supervised normally open contact

and three Command Input Circuits activate on contact closure. CMD 1 and CMD 2 provide termi-

nals for NAC input and output to allow installation of the audio panel anywhere along the NAC cir-

cuit being used to activate it. Options via the Command Inputs allow one 60 second message, two

30 second messages, three 20 second messages, four 15 second messages or five 12 second mes-

sages.

The ACC-25/50ZS and ACC-25/50ZST include an ACC-ZPMK Zone Page Module with keypad

and an ACC-ZSM Zone Splitter Module. These modules provide up to eight speaker circuits that

may be manually or automatically activated.

The ACC-25/50ZST includes an ACC-FFT Fire Fighter Telephone Module with keypad which

provides indications of phone activation, remote page activation, remote microphone activation and

corresponding trouble conditions. Additionally, up to 24 telephone circuits can be annunciated at

the ACC-FFT by connecting addressable monitor modules to the optional FPJ-F or RPJ-F Remote

Page Jacks.

Significant technological enhancements set the ACC-25/50 Series apart from other voice panels.

These enhancements include full supervision in both active (alarm or music) and standby condi-

tions. Supervision is provided for:

 amplifier outputs

 field wiring (shorts and opens)

 message generator

 all tone generators

 microphone

 telephones (optional)

If the message generator fails, the system automatically reverts to the primary tone generator. If the

primary tone generator fails, one of three backups become enabled.

Power is fed independently

to each amplifier so that a short circuit in one amplifier will not shut

down the other. Full output power of 25 watts per amplifier is generated while in a low battery con-

dition. Power is not diminished when the optional 70 V

RMS

transformer module is installed. Audio

is amplified utilizing modern integrated circuits as opposed to transformer technology. This pro-

vides for very low signal distortion for crystal clear audio.
